Went to buy a 2009 accord 2.2 139k But it has this warning it drives OK Has no engine management light a cheap obd tool didn't say anything But it seems to relate to fuel injection system. I can't take it to a garage as its not my car the car is priced accordingly . Could this be a real headache should I stay clear or u think it will be something fairly manageable in your experience of hondas Thanks in advance There is very little regarding this on Google
